Summary:The invention provides a video lag identification method and device, and terminal device, and is suitable for the technical field of video processing, and the method comprises the steps: modifying a monitoring state into a second state when the monitoring state of a video is a first state and a face exists in the video; if the video is in the second state, sampling the video to obtain N first frame images; if the image difference degree among the N first frame images is smaller than a first difference threshold value, taking the earliest sampling moment as a jamming starting moment, and setting the monitoring state as a third state; if the monitoring state is a third state, sampling the video to obtain M second frame images; and if the image difference degree between the M second frame images is greater than or equal to a first difference threshold, taking the latest sampling moment as a jamming termination moment of the video, setting the monitoring state as a first state, and identifying a jamming time peri
